How much is the Percentage 📊

What is the GPA 🎯

Which Letter Grade it is (A+, A, B, C…) 🏅

And the best part is, all of this is free and online – no installation required.

How to Calculate Your Final Grade

Enter the marks for each subject

• Example: English (80/100), Math (70/100), Science (90/100)

Percentage
Formula:

👉 Percentage Formula:

\[ \text{Percentage} = \frac{\text{Total Marks Obtained}}{\text{Total Maximum Marks}} \times 100 \]

---

👉 GPA Formula:

\[ \text{GPA} = \frac{\sum (\text{Grade Point} \times \text{Credit Hours})}{\sum \text{Credit Hours}} \]

Example:
(80+70+90)/300×100=80%(80+70+90) / 300 \times 100 = 80\%(80+70+90)/300×100=80%

Assign the Letter Grade

• A+ = 90% and uper
• A = 80–89%
• B = 70–79%
• C = 60–69%
• F = Below 60%

Example: 80% = Grade A

If you want the GPA

Multiply each subject’s credit hours by the grade point

Add them all together and then divide by the total credits

Final Result = your overall performance in percentage + letter grade + GPA

Example: Final Exam Grade Calculation

Let’s say you have 4 subjects – English, Math, Science, and History. Each subject has different weightage and marks.

Subject	Weight (Final %)	Marks Obtained	Max Marks	Weighted %
English	25%	80	100	20%
Math	30%	70	100	21%
Science	25%	90	100	22.5%
History	20%	60	100	12%

Step 1 – Calculate the percentage for each subject

English → (80 ÷ 100) × 25 = 20%

Math → (70 ÷ 100) × 30 = 21%

Science → (90 ÷ 100) × 25 = 22.5%

History → (60 ÷ 100) × 20 = 12%

Step 2 – Add them all

Final Grade % = 20 + 21 + 22.5 + 12 = 75.5%

Step 3 – Determine the Letter Grade (General Scale)

A = 80–89%

B = 70–79%

C = 60–69%

F = Below 60%

👉 Here, 75.5% → means Final Grade = B

Example Table – Calculating Grade from Percentage

Marks (%)	Letter Grade	Performance
90% – 100%	A+	Excellent 🎉
80% – 89%	A	Very Good 👍
70% – 79%	B+	Good 🙂
60% – 69%	B	Average 😐
50% – 59%	C	Pass 😅
Below 50%	F	Fail 😔
